Master Trooper J. A. Walker was 60 years old and had been with Virginia State Police since 1963. He lived and worked in Dinwiddie since 1986.

Another trooper responded to a call of shots fired and found Trooper Walker's patrol car in the woods off the right side of the highway. The responding trooper saw a man standing outside Walker's car and repeatedly firing into it, according to VSP Spokesperson Corinne Geller. The responding trooper shot at the man, who ran into the woods. He was arrested 40 minutes later by the Dinwiddie County Sheriff's Office and is now in State Police custody. Charges are pending and his name is not yet being released.
